Oriontek has some of the most energetic and passionate coworkers I've ever had. This place is full of young people with love for their work. I've been working for one of our most important clients (Cevercevería Nacional Dominicana), and the experience has been great so far.

I'm an essential part of this team. I've been working extensively on refactoring code to reduce development time in the large-scale, fixing security holes that we noticed on the go, decreasing apps sizes by 30%, and improving the apps launch time performance drastically.

Some of my responsibilities as a Mobile Developer at the team of Colmapp are:

• Maintaining the codebase for both applications (iOS and Android) using Swift and Kotlin.
• Implementing UI/UX mock-ups specified by our designer.
• Coding based on standard patterns on the industry.
• Coding tests.
• Fixing bugs.
• Delivering updates to the stores.

These following technologies were used: Swift, Alamofire, MVP Pattern, Kotlin, RxJava

Bonanza was looking for moving their business to the mobile industry, and I was more like a consultant the firsts months because they didn't know where to start or what are the best practices on the server-side for mobile solutions. After that, we started with mobile clients. I almost coded the iOS version entirely, but there are more tasks to complete in the web service, so we're still working closely, but I just only offer my services as a consultant and freelance developer.

My responsibilities as an iOS developer were:

• Coding iOS app from scratch.
• Coding unit tests.
• Keeping the codebase up to the current standards on the industry.

The following technologies were used: Swift, Alamofire, VIPER, BrightFutures, Swinject.

At Caribe Media, I had the pleasure to work with excellent and dynamic people that helped me grow on my professional path in an incredible way.

I was one of four mobile developers that were developing an app for a new prestigious client at that time. My role was crucial because they needed someone who works fast and reliable, it was necessary to build something that would last in time, and that would scale. We achieved that even with our lack of experience at that moment. The enthusiasm was the key to success because every member of the team, including myself, were extremely committed to creating something up to the standards of the industry. ClaroTV is one of the projects I am more proud of because I was there since the first sketches until it was a reality.

My main responsibilities were to create and to maintain amazing mobile apps that are currently leading the Dominican mobile industry.

• Coding the app from scratch based on the client's requirements.
• Implementing successfully the client's UX/UI designs.
• Releasing apps to the stores.
• Fixing bugs.

I used the following technologies: Android, iOS, MVP Architecture, Java, Dagger, Swift 3.x, Swift 4.x, Alamofire, RxJava, MQQT.
